Well I seem to have pretty thoughly bricked my poor tab.
Without going into to much detail, I should be more careful with .pit files and ODIN heh...
The tab itself appears totally dead, no boot, no back light, no matter how long you hold the power button / vol button combos.
When you plug it into a computer, it shows up as QHSUSB_DLOAD, and cannot find a driver.
ODIN and HEMIDALL don't see it at all.
I managed to find a QHSUSB_DLOAD driver of some sort, and using QPST was able to see that it was a com port, but I can't do anything past that.
Any of the tools in QPST say they cannot be used because the device is in download mode.
Anyways, pretty sure its gonna have to go to samsung to be fixed.
Which blows, because were pretty sure our next test will be successful, but of course who knows
